operator==operator!= (直到 C++20)

 

定义于头文件 <memory_resource>
bool operator==( const std::pmr::memory_resource& a,                  const std::pmr::memory_resource& b ) noexcept;	(1)	(自 C++17 起)
bool operator!=( const std::pmr::memory_resource& a,                  const std::pmr::memory_resource& b ) noexcept;	(2)	(自 C++17 起) (直到 C++20)

比较 memory_resource a 与 b 的相等性。 两个 memory_resource 相等，当且仅当从一个 memory_resource 分配的内存可以从另一个 memory_resource 解分配，反之亦然。

!= 运算符是从 operator== 合成 而来。

(自 C++20 起)

返回值

1) &a == &b || a.is_equal(b)

2) !(a == b)

is_equal
